Updated Statistics on Organic Tree Fruit Production and Other Crops
Two new reports provide up-to-date information on organic crop acreage. One report details all the certified and transitional acres in Washington State by crop. The other report provides the 2002 acreages for organic apples, pears and cherries in Washington State, including apple and pear varieties. These reports complement the more detailed analysis in "Current Trends in Organic Tree Fruit Production - 2001" that covers national and international trends as well. All reports are in PDF format. Produced by D. Granatstein, WSU Center for Sustaining Agriculture and Natural Resources.

Soils and Fertilizers
Outline of a Master Gardener Seminar by Jennifer Moore (formerly WSU-TFREC). "Soils are complex mixtures of minerals, organic compounds, and living organisms that interact continuously in response to natural and imposed biological, chemical, and physical forces."

Estimating Water Use by Plants: Evapotranspiration Calculator
The use of water by plants can be estimated by calculating what is known as potential evapotranspiration (pET). This is the possible loss of water through evaporation and transpiration. Transpiration is the movement of water through a plant from the soil into the roots, up the stem, and out through the leaves. Simple calculations of pET can be based on sun, wind, temperature, and humidity.


A Field Guide to Experimental Designs
The term experimental design is fairly generic and is best defined within the field of research in which it is used. Most of the designs illustrated here are statistical layouts used in agricultural, environmental, and other biological research.

Statewide Research and Extension Staff for Tree Fruits and Grapes--PDF format
A tad out-of-date (a to-do project) list of the tree fruit and grape researchers and extension agents statewide within the State of Washington. This is in PDF format (a reader is available from
